Question

I have multiple UITextViews with corresponding .txt files. I’m reading them with NSString’s

stringWithContentsOfFile

but I don’t know the path where I should put my files. If I put it to /tmp/ on my Mac, it works in Simulator, but, of course, doesn’t work on the actual device. So where should I put the files, so they’ll work on both Simulator and actual Device.

Add them as resources to your project and you’ll be able to load them from your application bundle using path:

NSString* filePath = [[NSBundle mainBundle] pathForResource:@"filename" 
                                                            ofType:@"txt"];

If you want to make these files editable, though, you can keep them in Documents folder in application sandbox. To get its path you can use:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
                                                        NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; 

So workflow in this case may be the following:

1. Check if required file is present in documents folder. If no – copy it there from resources.
2. Read data from file (from Documents folder)
3. Save updated data to file (in Documents folder) if needed
